Description
- 1. Field of the Invention
- The present invention generally relates to an electrical connector, and more particularly to a board-to-board connector assembly.
- 2. The Related Art
- A conventional board-to-board connector assembly includes a receptacle connector and a plug connector. The receptacle connector has a plurality of receptacle terminals each having a contact portion, and the plug connector has a plurality of plug terminals each having a contact arm. When the plug connector is mated with the receptacle connector, the contact portion electrically contact the corresponding contact arm to make the receptacle terminal and the corresponding plug terminal electrically interconnected. However, the receptacle terminal contacts the corresponding plug terminal merely in one single point. As a result, when the board-to-board connector assembly is shaken in use, the contact portion is likely to depart from the corresponding contact arm that makes signal transmission between the receptacle terminal and the corresponding plug terminal broken easily. Therefore, a board-to-board connector assembly capable of overcoming the above-mentioned problems is required.
- An object of the present invention is to provide a board-to-board connector assembly including a receptacle connector and a plug connector. The receptacle connector includes a receptacle housing defining a plurality of first passageways and a plurality of first terminals received in the respective first passageways. Each of the first terminals has a first base portion located in a bottom of the receptacle housing, an elastic arm extending upward from the first base portion and a first contact arm spaced away from the elastic arm. The elastic arm oppositely defines two first contact portions. The plug connector is mated with the receptacle connector, and includes a plug housing defining a plurality of second passageways and a plurality of second terminals received in the respective second passageways. Each of the second terminals has a second base portion located in a top of the plug housing. The second base portion extends downward to form a second contact arm and a third contact arm spaced away from each other. The second contact arm defines a first contact means facing the third contact arm and a second contact means opposite to the first contact means. The third contact arm defines a second contact portion towards the second contact arm. Wherein the elastic arm of the first terminal is disposed between the second and third contact arms of the corresponding second terminal to make the first contact portions electrically contact the first contact means and the second contact portion respectively, the first contact arm electrically abuts against the second contact means. Such that ensures the first terminal and the corresponding second terminal electrically connected with each other steadily even if the board-to-board connector assembly is shaken in use.
